Features / Pre-sort Dropship

Pre-sort dropship.
Skip the network. Pay the lowest postage USPS offers.

Mail tendered at an origin BMEU travels through the entire USPS sortation network — NDC, SCF, DDU — before it reaches the carrier route. Mail tendered at a regional entry facility skips the upstream hops. The deeper the entry point, the deeper the postage discount and the faster the delivery. DirectMail.io coordinates the freight, calculates the per-drop entry mix, and nets freight against postage savings — so the manifest shows the actual all-in economics. Pieces qualify for the lowest postage tiers USPS offers, in-home dates compress by one to three business days, and the team never touches a freight broker. The presort drop-ship industry calls this dropship — same idea, deeper postage.

How it works

Five steps. Net economics. Compressed delivery.

  1. 01

    Presort identifies destination concentration

    After standard presort, the platform analyzes the drop's destination distribution. Pieces concentrated to specific NDCs, SCFs, or DDUs get flagged as drop-ship candidates — the deeper the entry point, the deeper the postage discount.

  2. 02

    Drop pools by entry point

    Pieces destined for the same regional USPS facility (NDC, SCF, or DDU) bundle together for freight. The platform calculates the optimal entry mix per drop — sometimes a single entry point, sometimes a multi-stop freight route across several facilities.

  3. 03

    Freight coordinates to the entry facilities

    DirectMail.io coordinates the freight directly to the qualifying USPS entry facilities. No third-party logistics broker required, no separate freight contract for the team to manage. Freight cost is netted against the postage savings on the manifest.

  4. 04

    Mail tenders at the entry facility — skips the network upstream

    Pieces tendered at an NDC skip origin entry sortation. Pieces tendered at an SCF skip both NDC and origin entry. Pieces tendered at a DDU skip the entire upstream network and go straight to the carrier route. Each step skipped earns a deeper postage discount.

  5. 05

    In-home dates compress; postage drops

    Two outcomes. First, postage on drop-shipped pieces lands at the lowest USPS rates available — meaningfully below origin-entry presort. Second, in-home dates compress because the mail bypasses upstream sortation hops. Faster delivery, lower postage.

Why it matters

Why entry depth is the cheapest postage lever.

Origin-entry presort gets the automation discount tier on the postage. Drop ship adds a destination entry discount on top — same piece, same automation tier, lower per-piece rate because the postal service does less network handling. The math is straightforward: skip a sortation hop, pay less for the piece. Skip more hops, pay even less.

The lever almost no shop uses well is the per-drop entry-mix optimization. A 50,000-piece drop with concentrated destinations may have 8,000 pieces that justify a single SCF tender, 12,000 that justify DDU tender to a handful of post offices, and 30,000 that ride at standard origin-entry. Per-piece routing lets each segment of the drop ride the optimal entry. A flat "drop-ship everything" or "drop-ship nothing" decision leaves money on the table either way.

And the secondary win is throughput. Pieces tendered at the DDU enter the carrier route the same morning. Pieces tendered at the SCF enter local sortation that day. The compressed in-home window matters most for campaigns with timing-sensitive coordination — limited-time offers, event invitations, scan-trigger email co-landing — where every day of delivery delay erodes the conversion rate.

Per-drop
Entry-point optimization runs per drop, not per shop. The platform calculates the optimal mix of origin-entry, NDC, SCF, and DDU entry per piece based on actual destination distribution and net freight economics. Pieces ride the deepest entry that pencils out for that piece.

Use cases

Where drop ship earns its keep.

  • National brand campaigns with regional concentration

    Brand campaigns covering most U.S. metros produce enough volume per NDC and SCF that drop-ship economics work cleanly. The postage savings on a 250,000-piece national drop versus origin-entry presort is meaningful five-figure money.

  • Time-sensitive promotional drops

    Limited-time offers and event invitations benefit twice: lower postage and faster delivery. The compressed in-home window improves response on time-bounded campaigns where every day of delay costs conversions.

  • Scan-trigger coordinated campaigns

    For campaigns built around USPS Scan Trigger co-landing of email and mail, predictable in-home dates make the trigger choreography work. DDU-entry drop ship narrows the variance to the smallest possible window.

  • Multi-drop recurring programs

    Service reminders, loyalty drops, and other recurring programs run drop-ship optimization on every drop. The cumulative postage savings across a year of drops compounds into meaningful program economics.

Short answers. For implementation specifics on freight routing, multi-entry-point optimization, or commingle coordination, book a demo.

  • What is presort drop ship and how does it work?

    Presort drop ship is the practice of trucking presorted mail directly to a regional USPS entry facility — NDC (Network Distribution Center), SCF (Sectional Center Facility), or DDU (Destination Delivery Unit) — instead of tendering the mail at the origin BMEU. By skipping the upstream sortation network, drop-shipped mail qualifies for additional postage discounts on top of the automation tier presort earned, called destination entry discounts. The deeper the entry point, the deeper the discount.

  • What are NDC, SCF, and DDU entry points?

    NDC stands for Network Distribution Center — the USPS network's broadest regional sortation hub. SCF stands for Sectional Center Facility — a more localized sortation hub serving specific geographic regions. DDU stands for Destination Delivery Unit — the local post office where the carrier picks up the mail for delivery. Mail tendered at an NDC skips origin sortation; tendered at an SCF skips NDC and origin; tendered at a DDU skips the entire upstream network. Discount tiers compound the deeper the entry.

  • Is freight included in the cost — or is the team responsible for shipping?

    Freight coordination is handled by DirectMail.io. The platform calculates the optimal entry mix per drop, books the freight, and nets the freight cost against the postage savings on the campaign manifest. The team never touches a freight broker. The bottom-line economics on the manifest reflect the all-in cost — postage plus freight — versus what the drop would have cost at origin entry.

  • When does drop ship pencil out — and when does it not?

    Drop ship economics depend on volume per entry point. A drop with high concentration to a small number of NDCs or SCFs typically pencils out comfortably. A highly dispersed drop with low per-facility volume may not justify the freight cost for the postage savings produced. The platform runs the math per drop and only routes pieces to drop-ship entry where the savings exceed the freight cost. There is no "always drop-ship" or "never drop-ship" rule — the decision runs per piece, per drop, on actual economics.

  • How much faster does drop-shipped mail deliver versus origin-entry mail?

    Skipping upstream sortation typically compresses in-home dates by one to three business days, depending on the entry point depth and the geographic distance from origin. DDU-entry mail can deliver same-day to next-business-day after tender — the carrier picks it up at the local post office that morning. The faster delivery is what makes drop ship valuable for time-sensitive campaigns (limited-time offers, event invitations, scan-trigger coordination) beyond the postage savings.

  • Does drop ship work for all mail classes and piece types?

    Drop ship discounts apply primarily to USPS Marketing Mail letters and flats — the bulk of commercial direct mail. First-Class Mail has narrower drop-ship eligibility and Bound Printed Matter has its own rules. The platform applies the appropriate logic per mail class on every drop, and the manifest reflects the actual qualifying entry points and discounts per piece.

  • How does drop ship coordinate with commingle?

    Commingle pools small drops into shared sort runs to qualify for automation tier minimums. Drop ship trucks the qualifying mail to entry facilities for additional discounts. The two work together: a small drop joins a commingle pool, the pool then drop-ships at the optimal entry points. Pieces from a single small drop can ride the deepest postage tier USPS offers via this combination — discounts that would be inaccessible to a small drop on its own.
